Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift lever supporting device for a shift gear of a vehicle transmission, in particular, a shift lever of a type arranged on a body floor.

[0002]

2. Description of the Related Art As a conventional shift lever support device,
For example, the technique disclosed in Japanese Utility Model Publication No. 3-1298 can be cited.

In this publication, the spherical portion of the shift lever is supported by the lever retainer so as to be shiftable and selectable. The lever retainer is rigidly fixed to the retainer bracket, and the retainer bracket is joined to the body floor of the vehicle with an elastic body for vibration isolation interposed therebetween. Therefore, the spherical portion of the shift lever and the elastic body are arranged offset in the longitudinal direction (vertical direction) of the shift lever.

[0004]

In the shift lever supporting device having the above structure, the operation reaction force acting on the spherical portion when the shift lever is operated is applied to the elastic body which is arranged offset from the spherical portion. It acts as a moment. Therefore, the component force in the vertical direction also acts on the elastic body based on the operation reaction force. This vertical force vibrates the body floor up and down, which contributes to the generation of abnormal noise when the shift lever is operated.

A technical object of the present invention is to provide an elastic body arranged on a plane in which an operating reaction force acting on a spherical portion of the shift lever when operating the shift lever is substantially parallel to the body floor and passing through the center of the spherical portion. The effective absorption is to suppress the vertical vibration of the body floor due to this operation reaction force and the generation of abnormal noise accompanying it.

[0006]

In order to solve the above-mentioned problems, the shift lever device of the present invention is constructed as follows. That is, the spherical portion of the shift lever is supported by the lever retainer for shift and select operations,
In the shift lever support device in which the lever retainer is supported by a member on the body floor side of the vehicle, a plurality of elastic bodies are interposed between the lever retainer and the member on the body floor side. Moreover, each of these elastic bodies is arranged substantially parallel to the body floor and on a plane passing through the center of the spherical portion of the shift lever.

[0007]

In the above structure, when the shift lever is operated, the operation reaction force acts on the spherical portion supported by the lever retainer, and this operation reaction force is immediately absorbed by the elastic deformation of each elastic body. It Therefore, it is possible to suppress the operation reaction force acting as a vertical force on the body floor as much as possible, and reduce the vertical vibration of the body floor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will now be described with reference to the drawings.

Embodiment 1 FIG. 1 shows a side view of a shift lever supporting device, and FIG. 2 shows a plan view thereof. In these drawings, on the upper surface of the vehicle body floor (floor tunnel portion) 10,
The retainer bracket 12 is attached. That is, the retainer bracket 12 has the connecting portions 14 at a total of four positions on the front, rear, left and right thereof, and these connecting portions 14 are attached to the bolt 1
6 are fixed to the body floor 10 respectively.

On the upper surface of the retainer bracket 12,
Front side (left side of drawing) and rear side (right side of drawing) of vehicle
In the above, two supporting portions 17 and 18 are integrally formed. And on both rear side support parts 18,
Both ends of the support rod 20 spanned between these are fixed by bolts 22, respectively.

The shift lever 40 has a spherical portion 42.
Are supported by the lever retainer 30 so that shift and select operations can be performed. The lever retainer 30 includes shaft portions 31 and 32 that extend in the front direction and the rear direction from a portion supporting the spherical portion 42, respectively.

The shaft portions 31 and 32 are formed substantially parallel to the body floor 10 and along an axis passing through the center of the spherical portion 42. Moreover, a pair of left and right ring portions 31a is integrally formed at the end of the shaft portion 31 extending in the front direction, and one ring portion 32a is integrally formed at the end of the shaft portion 32 extending in the rear direction. ing. Therefore, each of these ring portions 31
a and 32a are located substantially parallel to the body floor 10 and on a plane passing through the center of the spherical portion 42.

However, the central axis of each of the front ring portions 31a is set in the vertical direction, and the central axis of the rear ring portion 32a is set in the horizontal direction. The front side ring portions 31a are attached to the front side support portions 17 of the retainer bracket 12 via the elastic bodies 34, respectively.
5 and a bolt 36. Further, the ring portion 32a on the rear side has an elastic body
It is supported through 8.

As a result, the lever retainer 30 is supported by the elastic bodies 34 and 38, which are arranged substantially parallel to the body floor 10 with respect to the retainer bracket 12 and on a plane passing through the center of the spherical portion 42. ing.

A shift cable 50 is connected by a ball joint 51 to the end of the portion of the shift lever 40 extending downward from the spherical portion 42. On the other hand, a select cable 52 is connected to a lower end portion of a select lever 46 rotatably attached to a side portion of the lever retainer 30 by a shaft 48.

Therefore, the shift lever 40 has its spherical portion 42.
When a shift operation is performed in the front-rear direction of the vehicle with the fulcrum as a fulcrum, the shift operation force is transmitted to the transmission side through the shift cable 50. When the shift lever 40 is selected in the left-right direction of the vehicle, the select lever 46 is rotated in conjunction with this, and the select operation force is transmitted to the transmission side through the movement of the select cable 52 associated therewith. It

In the shift lever support device having the above structure, an operation reaction force acts on the central portion of the spherical portion 42 when shifting or selecting the shift lever 40. This operation reaction force is effectively absorbed by elastic deformation of the elastic bodies 34, 38 arranged on a plane that is substantially parallel to the body floor 10 and passes through the center of the spherical portion 42. Therefore, this operation reaction force is transmitted from the connecting portions 14 through the retainer bracket 12 to the body floor 10.
To be transmitted to the minimum. In particular, the operation reaction force hardly acts as a component force in the vertical direction at the location of each of the coupling portions 14, and thus vertical vibration of the body floor 10 is suppressed as much as possible.

Further, in the conventional structure in which the retainer bracket is connected to the body floor with the elastic body interposed, the lever retainer of the lever retainer is caused by a dimensional error in the connecting portion of the shift cable and the select cable with respect to the retainer bracket. When the mounting position is displaced, the elastic body is preloaded. When the elastic body is bent by this, the elastic characteristics are not fully utilized.

With respect to this point, in this embodiment, since the elastic bodies 34 and 38 are provided between the retainer bracket 12 and the lever retainer 30, dimensional error of the connecting portion of the shift cable 50 and the select cable 52 is caused. As a result, no preload is applied to the elastic bodies 34 and 38, and the elastic characteristics are always properly exhibited.
